The 34-year-old has confirmed his decision to retire from 50-over cricket in order to focus all his energies on the longer form of the game.

That sees the promotion of Alastair Cook to one-day skipper, while in a move which appears to signal the end of Paul Collingwood âs international career, Stuart Broad has taken over the captaincy of the Twenty20 side.

It means for the first time England will have a different man leading the side in each form of the game. But it is a risky move for Strauss, whose predecessors as Test captain Michael Vaughan and Nasser Hussain were both hastened into retirement after giving up the one-day job.

Asked if he could avoid a similar fate, Strauss conceded: âWell, I canât be sure, thatâs the simple answer.â

But outlining his determination to continue in his role until after the back-to-back Ashes series in 2013, he added: âI certainly hope Iâll be around to contest those two series.

Coach Andy Flower said: âEveryone is fully behind Andrew. He feels very comfortable with that, I feel very comfortable with that and these two young captains will learn a lot from him and I donât see any problem.â

Flower also revealed both Cook and Broad had undergone formal interviews, a process Kevin Pietersen also went through.

âThere was discussion about other candidates and Kevin was one of those but there was a rigorous interview process and weâre very comfortable with the decision made,â said Flower.

Collingwood, who retired from Tests after last winterâs Ashes, faces anÂ uncertain future but Flower said: âHe continues as a player but we believe it is time to move on.â
